To all whom it may concern:

Be it known that I, ISAAC N. ENRIGHT, a citizen of the United States, residing at San Francisco, in the county of San Francisco and Stateof California, have invented certain new and useful Improvements in a Com bined Gas-Seal Box and Washer, of which the following is a specification.

This invention relates to a combined gasseal box and washer, the object of the invention being to provide an apparatus of this kind which will be convenient in use and which will enable the washer and scrubber to be brought close up to the gas-generator without the interposition of long pipes and seals, such as are at present inuse, which pipes are liable to clog up with tarry matter not easy to be removed.

' In the accompanying drawings, Figure 1 is a side elevation, partly in section, of the apparatus. Fig. 2 is an end elevation, partly in section, on the line 2 2 of Fig. 1'. Fi 3 is a plan view. Fig. 4 is a section on the Tine (L 4 of Fig. 1.

Referring to the drawings, 1 represents the supply-pipe which supplies the gas to the washer and which may be of very short length and connected direct to the generator. The impure gas coming from the generator passes by said pipe 1 into a washing-chamber 2, having a part tion 3 extending downwardly from the top of the channel, the lower edge of said partition being slitted and formed into fingers or teeth 4, extending alternately downward and at right angles to the partition. The horizontally-extending teeth insure that the gas passes into the water away from the partition, so that it cannot ascend in contact with the surfaces of said artition and avoid being washed. In the arther compartment formed by the partition, is an overflow-opening 5, which determines the level of the liquid in the washer, this overflow being above the bottom of the partition 3. The gas is thus compelled to pass down into the water in the washer and between the teeth l, being thus minutely divided, and is thus thoroughly washed. The tarry and heavy residual matter washed from the gas sinks to the bottom, which slopes downwardtoward the front, at the bottom of which are provided the doors 7. The 1i hter impurities floating upon the surface 0 the water will be carriedoff by the overflow and by the pipe 8 into a sump 9, from which it is run off in the usual manner. The gas thus partly purified now passes over a wall 10, extending upward from the edge of the bottom of the first chamber, and thus passes into a second washing-chamber like the first. The lower portion of the wall 10 is formed with shelvin sides 6 to direct the impurities to the front 0 the doors 7. The teeth 11 of the second partition are formed finer and smaller than those of the first, this being ermissible .on account of the greater part of the lampblack and other impurities having been removed when the gas arrives at the second washing-chamber. eration is repeated, and it is to be understood that any number of such chambers may be provided as may be necessary. Upon the rear side of the second or farthest washer is erected the scrubber 12, of usual construction. The water from this scrubbenflows into the second or farthest chamber of the washer,

while the first chamber is supplied bywater from a pipe 13. I c1a1m 1. The combination of a washing-cham her, an overflow-pipe therefrom, an inlet into said washing-chamber, and a partition between said inlet and overflow-pipe,'extending downwardly in said Wishing-chamber to a point above the bottom, but lowerthan the overflow-pipe, its lower edge being formed with teeth extending alternately downward and at ri ht angles to the partition, substantially as escribed.

2. The combination of a tank, a wall separating the tank into two washing-chambers, an overflow-pipe in each washing-chamber, a partition extending downward in each washing-chamber to a point above the bottom and below said overflow-pipe, the lower edge of the partition being formed into teeth and the teeth of the second partition even finer than those of the first, aninlet for the water into, the first washing-chamber on the side of the partition therein opposite to the overflow-pipe, a scrubber upon and connected with the second washing-chamber behind the partition therein, and a pipe for supplying water into the first compartment of the first washing-chamber, substantially as described.

3. The combination of a tank, the bottom of said tank sloping downward to one side, a wall separating the tank .into two washingchambers, a door for each chamber, located in the said side close to the said bottom, an overflow-pipe in each washing-chamber, a partition extending downward in each wash- In this chamber the oping-chamber to a point above the bottom and below said overflow-pipe, and a suitable inlet and outlet for the water, substantially as described.

4. The combination of a tank, the bottom of said tank sloping downward to one side, a Wall separating the tank into two washingchambers, its lower portion being formed with shelving sides, a door for each chamber, located in the said side close to the said bottom, an overflow-pipe in each washing-chamber, a partition extending downward in each.

washing-chamber to a point above the bottom and below said overflow-pipe, and a suitable inlet and outlet for the Water, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
